Toll!
Die Figur war zu weit oben und
der Abstand zur Symmetrieachse
 war falsch.

Verschiebe hier:

A = (1, 5.5)
B = (1, 1.5)
a = Line(A, B)
C = (-1, 1.5)
D = (0, 1.5)
E = (0, 0.5)
F = (-1, 0.5)
Vieleck1, c, d, e, f = Polygon(C, D, E, F)
G = (-2, 2.5)
H = (-1, 2.5)
I = (-1, 1.5)
J = (-2, 1.5)
Vieleck2, g, h, i, j = Polygon(G, H, I, J)
K = (-2, 0.5)
L = (-1, 0.5)
M = (-1, -0.5)
N = (-2, -0.5)
Vieleck3, k, l, m, n = Polygon(K, L, M, N)
O = (1, 3.5)
P = (2, 3.5)
Q = (2, 2.5)
R = (1, 2.5)
Vieleck4, o, p, q, r = Polygon(O, P, Q, R)
S = (2, 4.5)
T = (2, 3.5)
U = (3, 3.5)
V = (3, 4.5)
Vieleck5, s, t, u, v = Polygon(S, T, U, V)
W = (2, 2.5)
Z = (3, 2.5)
A_1 = (3, 1.5)
B_1 = (2, 1.5)
Vieleck6, w, z, a_1, b_1 = Polygon(W, Z, A_1, B_1)
